Abstract: A B S T R A C T      A dispersion strengthened aluminium alloy sheet is produced by casting an Al-Fe 1.1 - 2.5% alloy, optionally containing Si up to 2.0% and, optionally, proportions of other specified alloying constituents. The alloy is cast in the form of a slab at a growth rate in excess of 25 cms/min. and a thickness of less than 25 mms so that the intermetallics are formed in the slab in the form of fine rods of a diameter of 0.05 - 0.5 microns.  These rods are then segmented by reducing the slab by at least 60% by cold-rolling to develop a dispersion of fine intermetallic particles. By final annealing the rolled sheet at a temperature in the range of 250 - 400°C a sheet having a good combination of yield strength and formability is obtained (as indicated by a yield strength of greater than 15 ksi and tensile elongation greater than 15%).

Abstract: Abstract of the Disclosure Disclosed is method of preparing an essentially stable aqueous dispersion of from 25 to 50% or more rosin base material.  The method involves homogenizing an unstable aqueous dispersion of rosin-base material, a relatively small amount of which is in the form of a soap, such as the sodium soap, of the rosin-base material, the soap serving as a dispersing agent for the unsaponified rosin-base material.  The dispersions are useful in the sizing of paper.

Abstract: RADIO FREQUENCY PROTECTION CIRCUIT by John Willson Oades ABSTRACT OF DISCLOSURE     A diode switch device coupled between two circulators provides signal continuity around an active radio frequency circuit during a failure mode caused by a loss of local supply voltage.  Under a normal nonfailed condition, the diode switch short circuits the bypass path, thereby preventing the input signal from bypassing the protected circuit.          In the protected failure mode, the short circuit is removed and the input signal is conducted around the failed active circuit.

Abstract: ABSTRACT OF THE DISCLOSURE            Finely-mixed stock is produced in a headbox by delivering a multiplicity of separate stock streams at a relatively high velocity into passages defined between closely-spaced planar lamellae which extend parallel to the stock flow and oblique to a medial plane that lies axially and transversely of the fine-mixing stage that contains the lamellae.  The stock flows at relatively low velocity in finely-mixed condition from the fine-mixing stage to a discharge nozzle, the axis of which lies at a substantial angle to the axis of the fine-mixing stage.  The stock distribution and mixing section and the delivery nozzle of the headbox may be divided axially and transversely into two or more separate compartments for discharge of a jet composed of layers of the same or different stocks to form multi-ply webs,  Different fiber orientations in different layers of such a multi-ply web are obtained by orienting the lamellae in the different chambers at substantially different oblique angles to the aforementioned axial-transverse medial plane of the fine-mixing stage.

Abstract: ABSTRACT           An apparatus is disclosed for processing products aligned on a tape.  In the present embodiment, the products are shown to be beat recoverable sleeves which are conveyed to a control station for insertion of a terminal.

To accomplish the above, a drive having a friction coupling and a positive coupling are employed to convey the work through the apparatus.  A conditioned atmosphere process apparatus is employed for the heating of the sleeves and a controlled product feed apparatus controls the feeding of the work to the control station.

The filaments are positioned in crossing, overlying relation with adjoining filaments, said filaments essentially occupying individual, parallel, flat planes.  The filaments define first sets of generally parallel strands defining a first angular relation to said longitudinal axis and second sets of generally parallel strands defining an opposite angular relation to said longitudinal axis, a first filament of a first set being overlaid by a first filament of a second set, which first filament of said second set is, in turn, overlaid by a second filament of said first set, which second filament of said first set is, in turn, overlaid by a second filament of said second set.  The said relationship continues throughout the majority of the filaments of the first and second sets to define interleaving releationships, in which the filaments of each set overly the immediately-preceding filaments of the other associated set, and are overlaid by the immediately-following filaments of said other set, the majority of individual filaments thereof extending across 15 to 50 percent of the width of said filament bundle.
